visual callosum fibers in schizophrenia patients. Indeed, despite the established qualitative relationship between the integrity of the corpus callosum and interhemispheric transfer, as evidenced by the IHTT abnormalities exhibited by acallosal individuals; (Bayard et al., 2004), only one previous study (to our knowledge) has directly investigated their empirical relationship in healthy individuals. Westerhausen et al. (2006) estimated IHTT on the basis of the difference in P1-latency at electrodes O1 and O2 to unilaterally-presented visual stimuli, and paradoxically found that IHTT was negatively correlated with Mean Diffusivity in the splenium of the corpus callosum.
